Abstract:To reveal the influence of heat transfer and heat source temperature on system performance in finite time, and the theoretical basis of solar-aided coal-fired power generation system, the relationship between output power, efficiency and cycle parameters in finite time thermodynamic system was improved. The significance of each parameter and its influence on system performance were discussed in combination with the case of solar-aided coal-fired power generation system. The results show that the system design of 500 MW and 1 000 MW coal-fired generating units is reasonable, and the output efficiency is between C-A efficiency and ideal cycle efficiency. The integrated system efficiency is reduced to some extent. The performance of 1000 MW integrated system deteriorates under the coal saving mode, and the efficiency is lower than C-A efficiency. Therefore, the system process needs to be improved. The efficiency of 200 MW coal-fired power generation system before and after integration is lower than the C-A efficiency, indicating that the system process needs to be greatly improved.
